使用in case的两点特别注意
■in case 与in case of性质不同
in case 可用作连词和副词,而in case of 用作介词。如:
In case of fire, ring the bell. 如发生火灾,请按铃。
The wall was built along the river in case of floods. 沿江筑了堤坝以防有洪水。
有时两者可以互相转换。如:
In case I’m not here, ask my brother to help you.=In case of my not being here, ask my brother to help you. 如果我不在,可让我弟弟帮助你。
■in case与if有时意思不同
注意下面两个句子在意思上的不同:
I’ll come tomorrow in case Ann wants me. 明天我要来,以备安找我。
I’ll come tomorrow if Ann wants me. 如果安找我,我明天就来。
但是,介词短语 in case of…与 if there is…的意思却相同。如:
In case of accident phone 999.=If there is an accident phone 999. 如果发生事故,请拨电话999。
